PRINTING OR REGISTERING BEAM FOR WEIGHING-SCALES.

Specification of Letters Patent.

Patented VJuly 9, 190'?.

Application tiled January 23, 1905. Serial No. 242,377.

To all ywhom 'it may concern:

Be it known that I, EUG-ENE Bn'rz, a citizen of the United States, residing at Chicago, in the county oi Cook, State of Illinois, have invented certain new and useiul Improvements in Printing or Registering Beams l'or Weighing-Scales, oi which the following is adescription, reference being had to the accompanying drawing, and to the letters and figures ol relerence marked thereon.

My invention relates to an improvement in printing or registering beams tor weighing scales, and the object ol the invention is to provide certain improvements in the details oi such devices among which may be mentioned the arrangement oi type and the manner oi attaching the same to the beam, an improvement in the means ier impressing the card or ticket upon the tace oi the type.

The invention consists in various matters hereinafter described and referred to in the appended claims.

The invention is illustrated in the accompanying drawings, in which Figure lis a iront view showing a portion oi the iront oi the poise removed; Fig. 2 is the horizontal section on the line 6-G, Fig. 5; Fig. 3 represents details oi the plunger and operating mechanism', Fig. 4 is a modilication ol a mechanism for operating the plunger carrying the platen', Fig. 5 is a cross section through the poise and beam, illustrating one form of impressing mechanism; Figs. 6 and 7 are similar views, illustrating a modified iorm of impressing mechanism in different positions; Fig. S is a side view of the poise with the handle for operating the impressing mechanism; and Fig. 9 is a bottom plan view of the poise.

In these drawings, the main beam is shown at a, the main poise at b, the poise slide which carries the iractional beam at c, and tl is a rack on the poise slide. Meshing into the rack d is a pinion e, upon a vertical shait, operated by a thumb piece f. The type on the poise slide are represented at g. The number plate h on the main beam is beveled on its lower edge-to engage the beveled edge of the type bar i, and the type l bar i may be adjusted by loosening the screws in the number plate and sliding the type along as desired, and the type bar g is slotted at each end as shown in Fig. l, and held by screws v to allow oi adjustment. The poise slide c is gibbed to the main poise, as shown at p. lhe platen j which makes the impression is loosely )inned as at r, upon the plunger q, which plunger passes through the threaded stem or sleeve Z, and is held by the nut m. The handle k is attached to the stem l by the screw n, the stem Z being threaded through the iront wall oi the main poise, so that when the stem is turned the plunger and platen will be moved longitudinally toward the type bars, the platen being prej vented from. turning by passing through a slot in the plate s, which is preferably oi spring material, and acts as a stripping plate to prevent the ticket lrom adhering to the platen ol' the impressing attachment.

Fig. ii on Sheet l of the drawings represents a modification ol the means lor operating the platen, the plungerI q, to which the platen is attached passing through the iront extension ol the main poise, a long handle 'w being pivoted at y and cooperating with a rigid handle wf, the handles being held apart by a spring :t surrounding the plunger and bearing against the pin z.

As shown in Fig. l, as the poise is moved along by the rack and pinion, a spring t enga-ges in a notch in the-bar it, and holds it in position for printing. As shown in said ligure, the poises as set would indicate a load of 93,440 pounds, the reading being taken on the lett hand side of the poise as usual; the type bar adjustment above referred to being provided lor the purpose of allowing the reading at the edge ol' the poise to be the same as the printing which takes place :it the middle of the poise.

Referring to Figs. 6, '7, S and 9, the threaded stem l passes through a spring A, which is attached to the tip of the main poise b. The lower endoi this spring is iree to move in a recess E in the lower part C ol the poise b. The handle is represented at k and a stop pin B is provided to prevent the handle lrom turning too far.

The mode oi operation ol' the construction just described is as follows: When a ticket is inserted, the handle k is turned as shown in Fig. 8. About a quarter of a revolution brings the platen j up against the type, but not with suiiicient force to print, because the spring A has not yet been put under tension. Further movement of the handle will develop the orce ol the spring, as shown in Fig. G, so that the ticket is pressed more fnmly but with a yielding gradual pressure upon the face of the type, until at last the end D oi the spring A is brought up against the stop C at which time the whole iorce of the spring is developed.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:-

l. ln a printing or registering beam for weighing scales, the combination with a beam having a le( alongl its lower front face, of a type bar having outwardly tapered side edges, one oi which is adapted to engage th(` ledge on said beam and a securing plate with a beveled odge for engaging the other edge of said type bar and holding the same on said beam, and means eti-operating therewith whereby an impression may be taken l'rom said type: substantially as described.

2. In a printing or registering beam for weighingl scales, the combination with the beam, oi a poise sliding thereon and an impressing attachment carried by said poise and comprising a platen, a plunger, to which the sanne is loosely attached, a stem threaded on the poise, through which the plunger passes, and a handle for operating the stem; substantially as described. l

A printing or registering beam for Weighing scales, comprising a beam, a poise sliding thereon, and an impressing attachment supported by said poise and eomprising a platen, a plunger to which the platen is loosely attaehed, a threaded stem surrounding the plunger and threaded upon a part secured to the poise, a handle for operating the stem, and stripping plate through which the platen is adapted to project; substantially as described.

4. In a printing or registering beam for weighing scales. in combination With the beam having type thereon, a poise sliding on said beam, a spring plate secured to said poise, a stem threaded through said spring plate, and a handle for operating the stem, a plunger passing through the stem and carrying a platen at one end, whereby when the handle is turned the movement of the stem will develop the force of the spring; substantially as described.

5. In a printing or registering beam 1 'or weighing seules, in combination with the beam having' type thereon, a poise sliding on said beam, a spring plate secured to said poise, a stern threaded through said spring plate, and a handle for operating the stem, a plunger passing through the stem and Carrying a platen at one end, and a stop for limiting the movement of the lower end of the spring; substantially as described.

In testimony whereof I affix my signature, in presence ol' two Witnesses.
